Summary

Summary:

My research focuses on the properties of solutions to singular stochastic (partial) differential equations, such as their Markovian semi-group, or their local times. These questions arise in the study of scaling limit of various discrete models such as wetting models, and a major challenge is to understand these properties in the light of the new tools provided by regularity structures and rough path techniques.

My PhD, which I defended in April 2019 under the supervision of Lorenzo Zambotti at Sorbonne Université in Paris, concerns a family of stochastic PDEs which arise as infinite-dimensional analogs of Bessel processes.
